I just send this of into a different direction, but i think it
is usefull for some people here as well:

Yes, Magnus hint with the book was very good. Its chapter 4
gives a nice overview of how it is done, but does not go too much
into the details. The other chapters cover a lot of the real world
issues that NTP in a nice and concentrated form.
For the details the book referes to  which covers the algorithm
for NTPv3 and  which covers NTPv4. There seem some typographical
problems with  though, which make me unsure about the formulas,
without really checking them, but  contains them without the
typographical problems. The book also mentiones , but i have
not had the time to have a look at it yet
